AUTOMOBILE-HEATER.

Specification of Letters Patent. Patented May 25, 1920.

Application led May 18, 1917. Serial No.' 169,403.

Toall whom it may concern:

Be it known that I, EUGENE H. HELLER,

a citizen ofthe United States, residing at Chicago, in the county ofCook and State of Illinois, have invented new and useful Improvements inAutomobile-Heaters, of which the following isha full, clear, concise,and exact description, reference being had to the accompan ing drawing,forming a part of this speci cation.

My invention relates to automobile heaters and guard, and, moreparticularly, to that type of heaters in which motor exhaust gases areutilized as the heating medium.

The main object of my invention is to provide a suitable support for aguard-plate forming a part of a radiator as characterized above, andarranged to prevent contact with the hollow radiator body, which maybecome very hot due to the passage of exhaust gases therethrough. Afurther object of .my invention is to provide an exhaust as heater whichis supported high enough rom the floor of the automobile to enable thefloor-board to be cleaned readily, with a fender adjacent and extendingover the heater body and which also is supported far enou h above Vthefloor-boardto ermit the ilooroard to be readily oleane A further objectis to provide a securing means for a guard-plate support alsoconstructed to secure the support of the radiator body to the floor ofan automobile, one securing means for both parts tending not only toeconomy and cheapness of manufacture,but also facilitating theinstalment of the radiator in the automobile by unskilled persons. Afurther object-.iste provide a guardplate support which shall partiallyinclose the radiator body support and conform to the general contourthereof, in order to resent a neat and compact appearance. nd a furtherobject is to provide a guard-plate support which shall be disposedbeneath the guard-plate and reinforced thereby, whereby an adequate suporting means is obtained with a minimum o weight and strength ofmaterial. Other objects will appear hereincorporated therewith, asindicated by dotted lines;

Flg. 2 is a side elevation of theradiator showing partly in section theguard plate and supporting means therefor;

Fig. 3 is an end elevation of the radiator' showing the means employedfor securing the same to the floor of an automobile; and Flg. 4: is adetail `sectional view taken on line 4 4 of Fig. 2 showing thedisposition of the guard-plate support under the guard plate. f

The preferred form of construction as shown in the drawings comprises ahorizontally-disposed hollow body 1 of cylindrical form terminating insemi-spherical hollow sockets or elbows 2 and 3, which are respectivelyformed integrally with pipes 4 and 5 adapted to conduct gas to and fromsaid body, as indicated `by arrows in Fig. 2. The pipes 4 and 5.arevertically disposed and provided with diametrically-oppositehorizontally extending supporting lugs 6, each of which has a screw-hole7 as indicated by dotted lines in Fig. 3. The socket 2 is provided witha valve 8, which may be turned a half revolution for regulating the Howof gas through the radiator, there being a segmental projection 9 onsaid socket for limiting the turning of said valve, as clearly shown.

The guard plate 1() is provided with a series of apertures 11 in orderthat heat may radiate freely from the body 1, and said apertures areartisticallyformed and arranged in said guard plate, with the view ofmaking the device ornamental as well as useful. The guard plate 10 issemi-cylindrical in form and substantially co-extensive with the y body1, including the sockets 2 and 3, and the ends of said guard plate areprovided with inwardly-extending flanges 12, which embrace the outeredges of guardlate supports 13, as shown in Figs. 2 an 3. This guardplate may be a sheet metal stamping. Each support 13 may be formed of anintegral metal bar bent to shape.

Each guard-plate support 13 is provided with a circular portion, whichis disposed under the guard plate 10 and riveted thereto, as shown inFig. 2', the flanges 12 serving not only to reinforce the supports butalso to conceal the joints between the same and the guard plate, thuseffecting a neat and rigid construction at a minimum of expense ofmanufacture. The circular portions of the supports 13 extend dowrnvardlyto within a short distance of the pipes 4 and 5 and thence vertically tolugs the vertical-portions being parallel and spaced slightly from thepipes 4 and 5. The circular portions of the supports 13 are concentricwith the'sockets 2 and 3, and the annular` space therebetween affordssuflicient clear-I ance between the guard plate 10 and the body 1 forthe circulation of heated air.

It will be seen that the parallel and circular portions of the supports13 conform to the general contour vof the pipes 4 and 5 and the sockets2 and 3, thereby producing a symmetrical design.

Extending horizontally from the lower extremities of the parallelportions of the supports 13 are lugs v14 having screw-holes e 15 whichregister with the screw-holes 7.

., Hoor 17 to permit the floor to be readily cleaned underneath thehollow body and l guard-plate without the necessity of removing them.

kWhat I claim as new is:

1. A device ofthe class described comprising a horizontally disposedtubular body and tubular elbows attached to the ends thereof and incommunication therewith, vertical pipes leading downward from saidelbows and yformed integral therewith, lugs extending laterally fromsaid pipes and provided with screw-holes, a guard plate disposedadjacent said body, and guard-plate supports secured to the ends ofsaidvguard plate and provided with screw-holes.regis ltering with saidfirst-namedscrew-holes.
